| Research Abstract |
In order to establish the way of simulate the fire behavior of high temperature and low oxygen microgravity conditions, the pool fire experiments were conducted in a stream of high temperature and low oxygen. The PMMA rods were melted to form a pool fire. High temperature low oxygen concentration gas flows coaxially around the pool fire. We have mapped the relationship between the critical oxygen concentration and coaxial flow with varying oxygen concentrations and air velocity, The flammability limit was formed U-shaped map. The data in the laboratory as an experimental control to create 6m fall class, observation of the flame spread experiments were conducted under low-gravity environment on fire. In addition, NIST developed the FDS (Fire Dynamics Simulator) ver.5 numerical calculations performed, and confirmed to be seen in numerical experiments with similar symptoms.
